I wish teachers would remember that just leaving lesson plans for a sub doesn't tell subs everything we need to know. I am a certified teacher who is having to sub this year and I love it when teachers leave me a detailed note about when they do this or that--like taking restroom breaks, lunch, where to pick them up from lunch, how kids get home, if there are kids that go to other classes throughout the day---stuff like that. Lesson plans do not tell me everything I need to know. Teachers also forget that just because they know what their abbreviation means doesn't mean a sub will know. Sorry just had to vent since I am really tired of subbing and really want a teaching job next year. When I do get my teaching job, if I ever need a sub I will leave a detailed note of what happens during the school day.
